The map shows Clinton cutting a wide swath of blue through the western part of Gwinnett, taking most precincts in the Norcross and Lilburn areas (some of the county's most diverse neighborhoods) then stretching all the way through the heart of Lawrenceville.
Clinton also won in all of the county's precincts with a majority of black voters, a significantly sized pocket on Gwinnett's southern tip.
The top 5 Gwinnett neighborhoods for Clinton:
- Martins E (Ferguson Elementary, 1755 Centerview Drive, Duluth): 88 percent
- Pinckneyville Q (Beaver Ruin Road Baptist Church, 1200 Beaver Ruin Road, Norcross): 85 percent
- Pinckneyville J (John Wesley United Methodist Church, 5320 Jimmy Carter Blvd., Norcross): 84 percent
- Martins D (Sweetwater Middle School, 3500 Cruse Road, Lawrenceville): 83 percent
- Pinckneyville N (Landmark Church, 3737 Holcomb Bridge Road, Norcross): 81 percent
Trump, meanwhile, dominated the northern and far eastern parts of Gwinnett like Buford and Dacula and Hoschton — in many cases, the county's whitest and most rural areas.
The president-elect also painted a significant strip of the county's southern half red.
The top 5 Gwinnett neighborhoods for Trump:
- Duncans C (Hamilton Mill UMC, 1450 Pine Road, Dacula): 75 percent
- Duncans B (Duncan Creek Elementary School, 4500 Braselton Highway, Hoschton): 73 percent
- Duncans D (Hamilton Mill Christian Church, 3809 Sardis Church Road, Buford): 72 percent
- Duncans A (12 Stone-Hamilton Mill, 3858 Braselton Highway, Buford): 72 percent
- Pucketts A (Bogan Park Community Center, 2723 N. Bogan Road, Buford): 70 percent
Gwinnett first became a majority-minority county — meaning non-white residents account for more than half of the population — in 2010. That wasn't nearly enough, however, to turn the county Democratic during 2012's presidential election.
Mitt Romney took 57 percent of Gwinnett's votes that year.
